good stuff for a first try..
Paulie pointed out some valid points like feathering. Another i recommend is not to use that texture filter - and if you which to.. blur it back, add noise and blur back again - I cant explain but i feel this looks better.
more attention to detail such as the eyes and mouth are importants - we humans look at a million faces every day and will pick up these you quickly.
For colouring faces a good base i feel is to use variations. Select the outline of the skin , removing eyes and teeth (leaving the lips as colour can then be added to them on top) and feather 1.5 to 6 depending on the size of pic. Go to variations, select midtones > instenity on 4 clicks > now select 2 yellow, 2 red, set intensity to 2 > 1 or 2 blues..
you could then use selective colour in the red and yellow channels to fine adjust.
Im not saying this is the only or even best way of doing it but is fast and simple..
Good luck with your next one..
